Ken O, a professor of electrical and computer engineering at the University of Florida, as well as principal investigator, has shown with his staff of 410 gigahertz circuit using CMOS technology, with which built many of the components of personal computers, mobile phones and portable electronic devices.
This frequency of 410 gigahertz eclipses the previous record for CMOS circuits set in February 2006 and 200 gigahertz. More importantly, is about 60 gigahertz higher than the previous record set using alternative but more expensive technology based on indium phosphide. Advanced industrial technology company Texas Instruments, known as the process 45-nanometer CMOS, serves as the basis for the new circuit.
"This is probably the first time in 30 years has shown that a silicon-based circuit has a higher operating frequency than one based on indium phosphide and similar compounds, "says O." It is exciting because if these circuits can be constructed efficiently, then you can build inexpensive detection systems and imaging for a wide range of applications. The result could reduce the cost for these systems by a factor of 100 or more. "
In the past, have produced extremely high-frequency circuits, but only with exotic materials are costly to manufacture. By contrast, CMOS technology is normally used in most circuits in the integrated circuit industry. This opens the door to widespread manufacture and distribution circuits high frequencies.
These new and viable applications include, for example, environmental monitoring equipment through continuous operation and high sensitivity to pollutants, noxious gases or bioterrorism agents. In the field of images, high-frequency circuits make possible techniques that can penetrate clothing to "see" hidden weapons or explosives.
high frequency circuits can also be used in medical equipment designed to facilitate early detection of skin cancers and others, and in industrial systems that monitor layers of the pills to make sure you have the thickness and uniformity appropriate.
